(Phys.org) —Enzymes are catalysts that speed up chemical reactions in living organisms and control many cellular biological processes by converting a molecule, or substrate, into a product used by the cell. ...

Researchers at Case Western Reserve University School of Medicine have uncovered the mechanism that enables the enzyme Lecithin: retinol acyltransferase (LRAT) to store vitamin A—a process that is indispensable ...

An enzyme that usually triggers strong allergic reactions now circulates in the veins of a group of mice without alerting the immune system. As INRS Énergie Matériaux Télécommunications Research Centre Professor Marc ...

The recipe for any given protein is written out as a series of 'codons', each of which encodes a particular amino acid. These amino acids are delivered via transfer RNA (tRNA) molecules, which feature an ...

By drawing together expertise from across a range of fields, the Eindhoven University of Technology's Institute for Complex Molecular Systems is on the verge of a breakthrough that could have significant ...

Organic catalysts are essential for a number of industrial applications, but their inability to work within the same system or in water means that their efficiency is somewhat limited. Researchers from the ...

A team of scientists from Pacific Northwest National Laboratory synthesized a chemical activity-based probe (ABP) that can provide new information about how living cells function. The new ABP is designed ...

Over the past decade, advances in genetic mapping tools have provided great insight into how DNA influences cell behavior. But genetics is only half the equation; much of cells' behavior is the result of post-transcriptional ...

The deconstruction of biomass is a pivotal process in the biofuel industry, but the enzymes that possess a significant role in the breakdown of biomass remain relatively unexplored. To this end, DOE researchers ...

One of the keys to commercialization of advanced biofuels is the development of cost-competitive ways to extract fermentable sugars from lignocellulosic biomass. The use of enzymes from thermophiles - microbes ...

Andrew Hansen grows wheat, barley, canola, and oats on his farm at Coomandook in South Australia, where his family has farmed the land for more than 60 years. But now the family's way of life is threatened.

Cells have a sophisticated system to control and dispose of defective, superfluous proteins and thus to prevent damage to the body. Dr. Katrin Bagola and Professor Thomas Sommer of the Max Delbrück Center for Molecular Medicine ...

There's a lot that can be done with a corn cob after the kernels have been removed. Farmers leave the cobs on the field to boost soil quality. Enterprising cooks use the cobs to make jelly. In China, the ...
